Stroke FAQ: What is stroke?

  • Stroke (or Cerebrovascular accident) is an emergency condition.
  • Sudden loss of function of a part of brain is caused by sudden brain damage either due to sudden stoppage of blood supply to brain or due to bleeding within brain.
  • The patient usually complains of paralysis of either one side of the body or one limb or sudden onset of inability to speak.

What is a mini-stroke or TIA?

  • TIA is transient ischemic attack, also called as ‘mini stroke’ or ‘warning stroke’, is a brief episode of brain dysfunction, caused by temporary blockage of artery in the brain.
  • Patients usually present with temporary loss of vision, difficulty in speaking, weakness on one side of the body, numbness of a part of a body.
  •  The blockage of artery is temporary, & symptoms are also temporary. The clot in the artery dissolves on its own or moves, so that the blood supply returns to normal and your symptoms disappear.

Are there different types of stroke, if yes what are they?

There are two types of strokes.

  • Ischemic Stroke – It is caused by blockage of artery in the brain due to blood clot.
  • Hemorrhagic Stroke – It is caused due to bleeding inside the brain due to rupture of weakened arteries (blood vessels). Aneurysm & AV malformations are two types of weakening of blood vessels.

What are the symptoms of stroke?

The symptoms depend upon the area of brain affected.

  • The most common symptoms (but not limited to) are weakness/inability to move one side of body (or one leg or one arm), deviation of one side of face, loss of sensations over a part of the body, slurred speech/difficulty speaking. There may be loss of consciousness & fall.
  • Other symptoms of stroke manifest according to affected area of brain.

Conservative management with the help of:

  • Monitoring of vitals
  • Supportive medications
  • Medications to prevent further clotting/bleeding, pain medications, antiseizure medications, medications to control blood pressure, medications to reduce pressure in the brain.
  • Nutritional support, nursing care, bed sore care, physiotherapy, speech therapy, psychological support etc.
